Unit 10 Waves Review

Which phenomenon occurs when a wave bends as it passes from one medium to another at an angle?

• Reflection

• Refraction

• Diffraction

• Absorption

OH.SCI.9-12.PS.EW.3.a

What is the main difference between reflection and refraction?

• Reflection changes the speed of the wave, refraction does not.

• Reflection occurs at a boundary, refraction occurs within a medium.

• Reflection bounces a wave back, refraction bends a wave as it passes through.

• Reflection absorbs the wave, refraction transmits it.
